About Converting Imperial gallon per Minutes to Cubic Millimeter per Hours
Imperial gallon per Minutes and Cubic Millimeter per Hours both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
cubic millimeter per hours = imperial gallon per minutes × 272765400
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per minutes equals 0.0000757681666667 base units, and 1 cubic millimeter per hours equals 2.777778e-13 base units, so dividing one by the other gives the direct imperial gallon per minutes-to-cubic millimeter per hours factor of 272765400.
Simple example
1 imp gal/min × 272765400 = 272,765,400 mm3/h
1 imperial gallon per minutes = 272,765,400 cubic millimeter per hours.
Real-world example
60 imp gal/min × 272765400 = 16,365,924,000 mm3/h
60 imperial gallon per minutes = 16,365,924,000 cubic millimeter per hours.

Frequently asked questions
How many cubic millimeter per hours are in 1 imperial gallon per minutes?
1 imperial gallon per minutes equals 272,765,400 cubic millimeter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per minutes to cubic millimeter per hours?
Multiply the imperial gallon per minutes value by 272765400. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per hours back to imperial gallon per minutes?
Use the reverse factor: 1 cubic millimeter per hours equals 3.666154e-9 imperial gallon per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per minutes?
Imperial gallon per Minutes (imp gal/min) is a unit of flow rate.
What is a cubic millimeter per hours?
Cubic Millimeter per Hours (mm3/h) is a unit of flow rate.
Is the imperial gallon per minutes to cubic millimeter per hours conversion exact?
Yes. Both imperial gallon per minutes and cubic millimeter per hours are defined by fixed standards rather than physical artifacts, so the factor of 272765400 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
